setLocation and setBounds are not working for JComboBox

[john price]

setLocation and setBounds are not working for JComboBox. All my other code is working perfectly fine though.
At the top of my code is:

JComboBox AIBoxLevel;

I tried this:

String[] AILevel = {"Low", "Medium", "Hight", "Genius"};
	AIBoxLevel = new JComboBox(AILevel);
	AIBoxLevel.setLocation(50, 195);
	AIBoxLevel.setSelectedIndex(1);
	this.add(AIBoxLevel);
	AIBoxLevel.addActionListener(this);

and this:

String[] AILevel = {"Low", "Medium", "Hight", "Genius"};
	AIBoxLevel = new JComboBox(AILevel);
	AIBoxLevel.setBounds(50, 195, 50, 50);
	AIBoxLevel.setSelectedIndex(1);
	this.add(AIBoxLevel);
	AIBoxLevel.addActionListener(this);

I also tried this:

String[] AILevel = {"Low", "Medium", "Hight", "Genius"};
	AIBoxLevel = new JComboBox(AILevel); //50, 195
	AIBoxLevel.setBounds(50, 195, 50, 50);
	AIBoxLevel.doLayout();
	AIBoxLevel.setSelectedIndex(1);
	this.add(AIBoxLevel);
	AIBoxLevel.addActionListener(this);

They all compile and run fine. The JComboBox pops up fine and works fine, just not in the right location.
Please help!

Don't even try to use setLocation/Size/Bounds. Learn to lay out a GUI the correct way.

edit: as you've already been told.

Also, you haven't taken care of following the convention in respect of variable names.

Honestly, if you're not prepared to learn from the responses to your queries, why bother to ask?

I added:

contentPane.setLayout(null);

to my code.
Result: blank screen

EDIT: I figured it out
Had to do:

setLayout(null);

Had to add to frame, not panel...Thank you!
